To all whom it may concern:

Be it known that I, OWEN D. McFAR- LAND, a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented certain new and useful Improvements in Methods of Making Shingle-Simulating Roofing Strips,

of which the following is a specification.

The invention relates to improvements in methods of making shingle-simulating roofing strips.

One of the objects of my invention is to provide a .new method, of making shinglesi'mulating strips, of ordinary asphaltic roofing material, whereby to cheapen the cost of production and to improve the artistic appearance of the finished strip Other and further objects of my invention will become readily apparent, to persons skilled in art, from a consideration of the following description when taken in conjunction with the drawings, wherein Figure 1 is a schematic representation, in elevation of a continuous sheet of felt, or other like base, undergoing the process of being made into shingle-simulating strips.

Fi 2 is a transversely extending shaft showmg a plurality of disks mounted thereon for removing the comminuted mineral material to expose the asphalt therebelow in 101%gltlldlllflll) extending stripes.

ig. 3 is a similar view showing disks for making the end stripes which are cut deeper into the sheet and are separately adjustable.

Fig. 4 is an end view of one of the shaft bearin s showing the manner of adjusting the dis s toward and from the sheet.

Fig. 5 is a plan view of the, sheet, showing the lon itudinally extending stripes and in dotted ines, the planes through which the sheet is to be cut to form the strips.

.Fig. 6 is a section taken on line 6 -6 of In all the views the same reference characters are employed to indicate some of the parts. I

I do not claim to be the first to produce a shingle simulating strip by covering a sheet of asphaltic roofing with a uniform coating of slate, or other mineral onmaterial, and providing stripes at intervals, extending transversely of the sheets in series, and lineally in a longitudinal direction of the sheet, to expose the asphalt therebelow and subsequently cutting the sheet transversely to form the strips. My invention relates to the particular method of producing the article.

embedded into the asphalt therebelow to produce the contrasting stripes between the areas coated with the slate. The stripes in the sheet, as heretofore produced bythe method referred to, are of indistinct outline and are not as strongly contrastable with the slate coated area to produce the best effect and furthermore the older methods pursued as heretofore described, are expensive and for this reason undesirable.

Inv carrying my invention into efi'ect, I pass the sheet of felt, or other suitable base, through a receptacle, such as 10 containing hot asphalt 11, which is heated by the furnace -12, therebelow. The sheet 13 passes over a roller' 14 into the tank 10 and around a roller 15 and over the roller 16. The doctors 17 and 18 remove the excessive quantity of asphalt from the sheet as it emerges from the tank 10. The sheet is then passed between the drivingrollers 19 and 20 and under the hopper 21 containing slate, or other like granular material, which is deosited upon the top surface of the sheet.

he sheet, then coated with slate throughout its entire extent passes over the roller 24 into a tank 25 containing water 26. The Water is circulated through the tank by suitable means, to maintain a uniform temperature and to carry away the heat coming from the sheet. The sheet passes under a suspended roller 27, within the tank, and over another roller 28, at the top of the tank. It is then passed CV61 the roller 29, under the roller 30 and over the roller 31, and again under the roller 32, in front of therotatable knives 33 and 34, which serve to cut the sheet transversely as on the lines 35, shown in Fig. 5, to provide the shingle simulating strips- 36. I v

A shaft 37 extended transversely of the sheet and is provided with disks 38, 39 and 40. These disks are of metal and have ends of the to provide sufiicient smooth faces, they may be either of steel or copper and when rotated rapidly in contact with the upper surface of the sheet they very effectively and thoroughly remove those portions of the slate coating with which they come in contact, leaving clearly defined outlines on each side, of the stripes 38', 39' and 40', which are parallel and extend longitudinally of the moving sheet. The shaft 37 are supported in boxes or bearing blocks 41, and vertically adjustable in the standard 42, by means of screws 43, and springs 44. By rotating the screws 43, at each end of the shaft 37, the relative height of the respective ends of the shaft may be adjustedsoas to. bring the disks 38, 39 and 40 more intimately into contact with the underlying sheet. A pulley 45 is secured to the outer end of the shaft 37 and affords a means of rotating the disks. The standards 42 may be supported upon pillars 46 Within which the shaft 29' carrying the roller 29, find bearing support.

The stripes 49 and 50 at the margin edges of the sheet are somewhat deeper than the stripes 38 to 40 inclusive. I therefore mount the'disks 51 and 52 on a separably adjustable shaft 53, which finds bearings in the standards 42 andis supported and adjusted in the same manner as the shaft 37, being provided 'with a driviug pulley 54 'secured to its outer end. The stripe 50 is also somewhat wider than the other stripes, so as room for a lap for the adjoining strip. I prefer to make the base portion, upon which the stripes 49 and 50 are made, somewhat thinner than the base portions underlying the stripes 38 to 40' in-.

clusive, so that the interlap of the stripes will not become so clearly apparent.

It will be observed that the sheet 13 is stretched tightly and smoothly over the roll 29 which confronts the disks 38 to 40 inclusive, so that there are no wrinkles or uneven surfaces presented to the disks, to facilitate the operation of the disks and to maintainthe stripes at uniform distances apart and of uniform width. "The sheet in like manner, is stretched over the roll 31 confronting the disks51 and 52. 4

aving described my invention, what I claim as new and desire to secure by Letters Patent is 1. The method of making shingle simulating-strips which consists in covering a long sheet with an asphaltic material, continuously coating the entire surface of said sheet with a layer of granular or flaky mineral to provide a substantially contrasting color to said asphaltic material, continuously I removing part of said mineral material to expose'the contrastingasphaltic material thereelow in a plurality of continuous and unbroken' stripes, longitudinally disposed on said sheet, continuously moving said sheet while of said sheetwith a transversely across said stripes into strips in the mineral is applied and removed, and cutting said sh'eet transversely across said stripes into strips in imitation of shingles.

2. The method of making shingle-simulating strips which consists in covering a relatively long narrow sheet with hot asphaltic material; coating the entire surface layer of granular or flaky material of substantially uniform color, passing said sheet under rapidly rotating disks to remove the mineral material thereby exposing the contrasting asphalt therebelow in arallel stripes, continuously moving said s eet and cutting said.sheet imitation of shingles. v

3. The method-of making shingle simulating strips which consists vin covering a, long sheet with hot asphaltic material, coat ing'the entire surface of said sheet with layer of granular or flaky material, continu-l ously removing part .of said mineral mate rial to expose the contrastin asphaltic material therebelow in a plura ity of continuous and unbroken stripes longitudinally disposed on said sheets, the stripes being located intermediate theedges of the sheets and also at the edges of the sheets, the material being removed to a greater depth at the edges of the sheet than for'the interme- 5 diate stripes, and cutting said sheets transversely across-said stripes into strips in imitation of shingles.

4. A shingle simulating strip comprising a backing having a layer of 'asphaltic mateo rial with one of. its faces covered in continuous zones with granular or flaky material to give it color, said zones being divided by contlnuous transversely extending stripes exposing the asphaltic material below them flaky material and said strip having continuous marginal end stripes, one of said end stripes being of substantially the same width as said transverse stripes, the other end stripe being much wider than the other no stripes to afford anoverlap, the base portion underlying the marginal stripes being thinner than that under the zone dividing strlpes.

5. A method of making roofing elements consisting in coverin a sheet with an adhesive coating, applying a layer of granular materiallpver' said coating of a different color than said coating, continuously removing part of said granular material in.a plurality of strips to expose the contrasting color of said coating in a plurality of areas on said sheet, continuously moving the sheet while the granular material is being applied and portions thereof removed. v,
